The packaging method of lithium battery depends on the shell material it uses. In general, only lithium pouch batteries will use aluminum laminate film and heat sealing. The metal cans batteries are usually sealed by laser welding. Aluminum laminate film generally has three layers, respectively nylon layer, Al layer, PP layer. Nylon layer is to ensure the appearance of aluminum laminate film,...

Materials Material selection is the first factor affecting the performance of lithium-ion batteries. If you choose the battery material with poor cycle performance, even if the process is reasonable and the production is perfect, the cycle of the cell can not be guaranteed. And with better materials, the cycle performance may not be too bad even if there are some problems in the subsequent product...
